.SAFETY INCLINE can p Application tiled Hay 28,

This inventionrelates to cars of that type operating on inclined planes and with thecars lowered by gravity and'raised by means of a pulling cable, butmore particularly'the invention relates to an automatically operable safety brake for the car, and has for its object to provide, in a manner as hereinafter set forth, means operated from the draft bar of the car for impacting against theties of the track to arrest movement of the car when the pulling cable therefor breaks or becomes slack. Y

Further objectsof the invention are to provide, in a manner as hereinafter set forth, a

, car of the class vreferredto provided with a safety device to arrest movement of the car when occasion requires and which is simple in its construction and arrangement, strong, durable, compact, automatic in its action, thoroughly eiiicient in its use, readily installed with respect to the car, and comparatively inexpensive to set up. Y

With the foregoingl and other objects in view the invention consists of the novel construction, combination and arran ement of parts as hereinafter more spec cally described and illustrated in the. accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood'ethat changes, variations and modifications can be resorted to which fall within the scope of the claims hereunto appended.

Referring to the drawings in detail-1 de- 1927. Serial No. 195,078. Y

notes a seriesfof spaced ties upon which is secured a pair of track rails 2, 3 which lprovides the track upon which the car, referred to fgenerally by the reference character 4, travels. y

The car 4 comprises a rectangular body portion in the form of a frame and. which consists of a pair of side bars 5, 6 and a pair of end bars 7, 8. The end bars 7, 8 are positioned inwardly with respect to the ends -of the side bars 5, 6. Each side b ar `has secured to the lower edge thereof a pair of bearings and.

the vbearings of one pairare indicated 'at 9 and the bearings of the other pair at 10'. The bearings on the side bar 5 oppose the bearings on the side bar 6. Each pairv of opposed bearings have journaled therein an-axle 11 which projects beyond each of the side bars and has mounted thereon a wheel 12. Mounted onthe top of the frame, as well as being secured thereto, lis a platform 13 provided with a seriesv of transverse seats 14. Theendbar 7,

provided for the passage of a springy con-V trolled draft bar 17 which each of the bars7, 8.

The lower edgeof the side bar 5 is formed projects beyond vcentrally thereof isiprovided with a tran'swith a series of spaced bearings, vthree in'` number and indicated at '18, 19 and 20. Secured'to the lower edgeof the side bar 6 isa' series of spaced bearings, three in number and indicated at 21, 22 and 23. The bearings 18, 19 and 20 oppose respectively the bearings 2l, 22 and 23. Journaled in the bearings 1,8,l

21 is a rock shaft 24. Journaled in the beari ings 19, 22` is a rockshaft 25 and journaled in the bearings 20, 23 is a rock shaft 26. The

rock shafts extend transversely with respect to the car body or frame and do not project V beyond the side bars 5, 6. The rock shafts 24 and 25 are arranged between the axles 1,1 and 'the' rock shaft 26 is positioned between an axle 11Y and the end bar 8.

Keyed to the rock shaft 24 in proximity t0 vthe side bar 5.and alsorin proximity to the side bar 6 is a socket forming member and which are indicated at 27 28. Keyed to the rock shaft 25 and in proximity to the side bar 5 and side bar 6 is a socket forming member and which are indicated at 28', 29. Keyed to the rock shaft26 in proximity to the side f V'41. Formed integral-with the `body portion bar 5 and in proximity to the side bar`6 is a socket forming member and which are indicated at 30, 31. he construction of each of said-socket forming membersl is clearly `shown in Figure 6 and each of which consists of a body portion .32 having the forward part thereof provided with an opening -33'for the passage of a rock shaft and with the wall of the opening` 33 grooved as at'34, for the reception of avkey, 35 which extends into the rock shaft. The rear part of the body portion 32 isformed with a socket 36 which opens at the rear end of the bodyportion 32 and has' 26 are res ectivel bifurcated crank arms 37 38 and 39 -Yand each of said crank arms consists of a tubular body portion 40, see Figure 5,and which is keyed to a rock shaft as at 40v andprojectingupwardly therefrom is a pairlofjspaced arms 42, 43 andeach of which in proximity tofits free end is provided with a'slot'44 of appropriate size. The crank arms 37, 38 and39extend at opposite sides of the` draft orpull bar 17 andare pivot-ally connected therewith by a headed pin' 45 which extends through the arms 42, 43, as well as the draft or pulll bar 17 and said pivot pin 45 is detachably connected in position by a cotter'piny 46 or other suitable retaining c means. The draft bar: 37 is provided with vslots or openings ofappropriate size for the passageof the pins 45V and with reference to Figure. one of the openings in shown in the draft barV 17 and is indicatedat 47.

ySecured in the socket forming members 27, 28 are rearwardly extending brake members i 48,49. Secured in the socket forming member 28,29 are rearwardly extending brake members 50, 51 respectively, and' secured in the socket forming members l30,k 31 are rearwardly extending brake members 52, 53 rcspectively. Each of the brake members with reference to Figure 6 is provided with a threaded terminal portion 54 which engages with the threads of the wall of the sockets `36. rPhe-brake members 48, 49 are of greater length than the brake members50, 51 and the length of these-latter-are reducedto provide a'clearance for the rear -axle'when said brake tion. Y. l v l c `Secured to the inner face ofthe side bar 5 is a pair of spaced inwardly extending lugs 55, 56and'secured totheinner face of the side bar 6 and extendingV inwardly therefrom is afpair of spaced lugs 57, 58. The brake members 48 and5() are connected respeci'sive-H ly to the lugs 55, '56 by a fiexible member 59.

'The brake members 49. 51 are connected respectively to the lugs 573, 58 by a iiexible memmembers-50,51 are arranged in inactive posil end bar 8 and extending inwardly therefrom are a pair of spaced lugs 61, 62 and the former is connected to the brake member 52 by a flexiblefmemberf63 andthe latter isvconnected mto,thebrakeminember 53 by a fiexible member 64. Thefiexible-members 59, 60, 63 and 64 4are inthe form of chains and couple the brake members ,withV the side bars 5, 6 of the car frame and `they Vfurther act to limit the lowering movements of said brake members.

Secured to the outer side of the end bar 8 abovethe opening 16, is a'bearingcollar 66,V

and which registers with an opening 67.`

formed in the end bar 8 above the opening V16. Fixedly securedl VtoV the draftbar 17 in proximity 'to theend bar 8 is a casting 68 provided with a tubular portion 69 arranged 1`n alignment" with the opening 67 .c Associated withthe draft bar 17 isa springv controlling device therefor, which not only includes'the casting 68, opening 67'and collar 66 butfurther includes a slidable bar 7 O which extends through the collar 66, opening 67 and tubular portion 69. The bar 70 projects rearwardly fromthe collar 66 and is provided at its outer end `with a nutA 71 constituting an abutment.

Positioned againstthe'collar 66 is a washer 7 2' and arranged against the nut 71- 1s a washerl 73. Mounted on the bar 70, is a controlling spring 74, and which is interposed between the washers-7 2, 7 3. The spring 74 normally functions to shift'the draft bar 17 rearwardlyv and Vthe forward movement `of the draft bar 17 isfhad byy the pulling rope which is indicated Vin dotted lines at 75, Fig-ure 1. The position of thepuil bar 157, when the pull-ropeA is .taut or when pulling the car up the track is indicated in dotted lines in Fig- Vure las atl76and when in such position'the ure 1, `whereby the crank arms 37, v38and 39 will be shifted to the full line'position shown in iiigurev 1 andlthebrakemembers will be loweredl to a position between Vtherties 1,.so when the car attempts to slide down the incline'the brake members-will abut against the t-ies and arrest the movement of the car. The bar 7()V is connected 4to the casting 68, .as 4at v70. Any suit-able means can be employed for shifting the draw bar forward to hold the retarders up,A should the car Vbe switched around on alevel/grade.V c

It is thought the manyadvantages of a safety car, in accordancey with this invention.

can be readily understood, andalthoughthe preferred embodiment of the invention 1 is as illustrated and described, yet it is to be understood that changes in the details of construction can be had which will fall within the scope of the invention as claimed.
